我院林业系教师、林业73—1班工农兵学员和黑龙江省森林调查第一、二大队协作,在教学,生产,科研三结合实践中,研究出了一种新的模拟样地法进行森林调查,取得初步成功。 1974年5至8月,先后在大兴安岭红花尔基林区和小兴安岭东北林学院凉水实验林场进行了试验,并在试验基础上,应用这种方法,对我院凉水实验林场进行了全面的森林资源清查,效果良好,精度和速度都达到了预定要求。模拟样地是按各样点测定树木的距离和株数,模拟成k个m边正多边形。将模拟成正多边形的样地视为样本单元,并称之为模拟样地
Our college forestry teacher, forestry 73-1 workers and peasants and soldiers and forestry in Heilongjiang Province, the first and second brigade collaboration, teaching, production, research three combined practice, developed a new analog plots for forest Investigation, achieved initial success. From May to August 1974, we conducted experiments in Honghua Kerchin District of Daxinganling and Liangshu Experimental Forest Farm of Donglin Forestry College in Xiaoxing’anling. Based on the experiment, this method was applied to conduct a comprehensive forest experiment Resource inventory, the effect is good, accuracy and speed have reached the predetermined requirements. Simulated plots are determined according to various points of the tree distance and the number of trees, simulated as k m regular polygons. The sample plots modeled as regular polygons are considered as sample units and are called model plots
